pub const unsafe fn _mm256_maskz_load_pd(k: __mmask8, mem_addr: *const f64) -> __m256dLoad packed double-precision (64-bit) floating-point elements from memory into dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). mem_addr must be aligned on a 32-byte boundary or a general-protection exception may be generated.
